In 2 series of experiments, the influence of population density and substrates on the growth and development of microgreens in oil radish was studied. In the optimum zone were crops with a density of 5 and 7 g of seeds per container with an area of 144 cm2. At higher seeding densities, the plants lagged significantly behind in growth. Their average height was 1.5 times less, and the average mass of microgreens per 1 g of sown seeds decreased 2-2.5 times. A new inert substrate, foam glass, was tested. Possessing high porosity, it provided an optimal water-air regime for plants. Comparison of growing microgreens on soil and foam glass showed the advantage of foam glass — the mass of plants on it was slightly larger. Despite the optimal air-water regime created by the foam glass, the diameter of the stones of 1.5-3 cm turned out to be excessively large and created inconvenience for growing microgreens.
